Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an automatic sewage discharge structure of sewage treatment equipment. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people. According to the source of sewage, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage, and medical sewage, while domestic sewage is sewage generated in daily life, which refers to a complex mixture of various forms of inorganic and organic matter, including: ① floating and suspended solid particles of different sizes; ② colloidal and gel-like diffusions; ③ pure solution. According to the nature of water pollution, there are two types of water pollution: one is natural pollution; the other is man-made pollution. At present, man-made pollution is the most harmful to water bodies. Water pollution can be mainly divided into three categories: chemical pollution, physical pollution, and biological pollution according to the different pollutants. There are many ways to treat sewage, which can generally be summarized as physical, chemical, and biological methods.

[0003] The automatic sewage discharge structure in sewage treatment equipment is widely used in the fields of metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electricity, and urban water supply, such as industrial wastewater, circulating water filtration, emulsion regeneration, waste oil filtration treatment, continuous casting water system in the metallurgical industry, blast furnace water system, and high-pressure water descaling system for hot rolling. It is an advanced, efficient and easy-to-operate automatic device. The automatic sewage discharge structure is an advanced filtering structure that automatically removes dirt and impurities to maintain the efficient operation of the filtering system. Its unique design and intelligent control system make it widely used in the industrial field. The automatic sewage discharge structure can reduce the energy consumption and maintenance costs of the system, extend the service life of the filter, and reduce the impact on the environment. The design is simple, easy to maintain and replace the filter element, which reduces the workload of maintenance personnel and improves the maintainability of the equipment.

[0004] During the process of realizing the present invention, the inventors found that the prior art had the following problems: 1. Most of the automatic sewage discharge structures currently in use often cause pipe blockages due to the large amount of solid impurities in the sewage; 2. Most of the automatic sewage discharge structures currently in use have pipes that are not sealed when there is no sewage, which may cause liquid or gas reflux. Utility Model Content
